Microsoft intends to create a single ecosystem for mobile phones, PCs and tablet devices.
Speaking at Microsoft's Worldwide Partner Conference, Andy Lees, president of Windows Phone, said the change to bring all the devices together into a unified ecosystem is about to happen.
"At the core of the of the device itself it's possible to be common across phones, PCs and TVs and even other things, because the price drops dramatically. Then it will be a single ecosystem," said Andy Lees.
"We won't have an ecosystem for PCs and an ecosystem for phones, one for tablets. They'll all come together," Lees added.
Lees continued: "We are aiming to provide coherence and consistency across the PC, the phone and the TV, particularly with Xbox."
At the same event, Lees said Microsoft's Windows Phone 7 mobile phone operating system is not appropriate for tablet devices.
Tablets require capabilities from the desktop version of Windows which cannot be supported by its Windows 7 phone OS. Functions such as printing and networking would be essential for tablet users, Lees said.
Nokia formed a partnership with Microsoft in February 2011 and will launch handsets running Windows Phone OS by the end of the year.
